Thank you for viewing. This is a T-shirt from Langlitz Leathers. I ordered and purchased it from their US headquarters, and it is made in the USA. (At that time, I was told that the items sold in Japan are planned by Langlitz JPN) Therefore, the size is M, but it is a bit large. For your reference, I have measured the dimensions below. Shoulder width: 47cm Body width: 50cm Length: 73cm Thank you.
